Important

minical never deletes or modifies events on its own.
If events are not displaying or syncing correctly, please check the following:

  • Your device settings may prevent events from being synced or fetched.
  • An Apple Calendar issue—the source from which minical retrieves event data—may have caused events to disappear from Apple Calendar.

1. Is the Sync setting set to "All Events"?

There is a possibility that the sync period of the event in the setting of iOS is shortened, such as the latest one month ago. Settings Please check the calendar sync settings of the Setting App Icon app

  2. (For iOS 18 or later) Tap "Apps"App Icon
  3. Tap "Calendar" Setting Calendar Icon
  4. Tap "同步"
  5. Tap "所有日程"

To isolate the cause of the issue, please check whether events appear in the Apple Calendar app.

Details: Where Is My Event Data Stored?

If no events appear in the Apple Calendar app

This is likely not a minical problem, but an issue with Apple Calendar or the external calendar service (iCloud Calendar, Google Calendar, Outlook Calendar) where minical stores events.
Please refer to the support site for your calendar service.

Reports of Disappearing Apple Calendar Events in iOS 18

Reports from other apps indicate that on iOS 18, events saved to Apple Calendar or iCloud Calendar may disappear.

How to Verify iCloud Calendar Data

Instead of your iPhone, open the iCloud Calendar website on an iPad or computer to see whether your events are still there.

If No Events Appear in iCloud Calendar

If an Apple-side issue has removed your iCloud data, minical cannot retrieve those events. Because we never store your event data, we are unable to restore it.

How to Contact Apple

If both Apple Calendar and iCloud Calendar show no data, we recommend contacting Apple Support:

*You can also chat with an Apple representative via the Apple Support app.
